Disperse ink‐jet inks: properties and application to polyester fibre

Abstract

Water-based ink-jet inks were prepared using press cake samples of two commercially available azo disperse dyes. The suitability of the inks for printing polyester fabric was evaluated via measurement of surface tension, conductivity, viscosity, pH and particle size distribution. Inks prepared by the proposed method fulfill most requirements for an ink-jet ink depending on the colorant structure, the dispersing agent and the alcohol used. The inks were applied to polyester fabric by both printing and dyeing and the fastness of the ensuing coloured samples was assessed. The fastness properties of the dyed and printed polyester samples were found to be very good to excellent and generally meet accepted customer requirements. Oil-in-water microemulsions containing the same colorants were also prepared. Their properties, which are crucial to the suitability for ink-jet ink, were compared with those of the conventionally prepared inks and were found to be improved, with the exception of conductivity, while surface tension remained within acceptable values.

Effect of Surfactants as Dispersing Agents on the Properties of Microemulsified Inkjet Inks for Polyester Fibers

“…By using the gemini type surfactant N-decanoyl-Nmethylglucamine (MEGA-10) (Fig. 1) as a dispersing agent [7,8] an increase of the emulsion stability over the 30 days was achieved with submultiple amounts of surfactant and organic immiscible solvent (Table 1). In Table 3 the conductivity, surface tension, viscosity and pH values of the formulation 4.1 with MEGA-10 over a period of 90 days are given.…”

“…Continuing previous work on the preparation and use of water-based disperse inkjet inks, conventional and microemulsified [7,8], the present work was undertaken in order to study the effect of the surfactant used as a dispersing agent on the properties of the disperse microemulsified inks. A commercial gemini type surfactant was selected for the preparation of a microemulsified inkjet ink [6,7].…”

Improve neural network‐based color matching of inkjet textile printing by classification with competitive neural network

“…Inkjet printing has unique advantages such as simplicity, high resolution, low use of water and energy, low waste, low cost of production, low equipment cost and saving time as compared to other printing methods . So, it is predicted that the application of inkjet printing in textile industry is growing rapidly and traditional methods of printing such as flat and rotary screen‐printing and roller printing may be replaced by inkjet printing technology in the medium term …”

“…[1][2][3][4][5][6][7] So, it is predicted that the application of inkjet printing in textile industry is growing rapidly and traditional methods of printing such as flat and rotary screen-printing and roller printing may be replaced by inkjet printing technology in the medium term. [8][9][10][11] Generally, printer devices are classified as continuoustone and halftone devices. In a continuous-tone printer, a uniform layer of colorant is generated and the concentration of each colorant is modulated to produce different intensity levels.…”

Digital printing of acrylic fabric with cationic dyes using conventional inkjet printer

“…Kosolia et al prepared water-based inkjet inks for printing of polyester fabrics. 7 The performance of the inks was evaluated by measuring of surface tension, conductivity, viscosity, pH, and particle size distribution. In addition, Aldib used photochromic dyes to print polyester fabric by a digital inkjet printing method.…”
